Manual Trans for 350TBI (V8)

Hello All
Not sure that this is in the right spot, but here goes...

I am looking to purchase a '90 YJ Sahara from a guy who did a V8 conversion on it. Chevy 350TBI. But he put in an auto trans... a rebuilt TH350 trans.

The problem is that I insist on a manual. Any suggestions on a good tranny for this V8? Any issues with this doing this changeover... or should I just run for the hills and not even get involved in all this?

thanks for your help

The nv4500 is prob the best option but there are many others. I have a Chevy nv3500 in mine. A problem that I have is the jeep master does not have enough a** to push the Chevy slave cyl and clutch. It doesn't fully disengage the clutch. Just remember it's a project and plan on spending money!

you could get a factory NV3500, NV4500 or SM465 all behind the TBI350. parts would be easy to source as they were all factory options. but non factory, there are other options as well.

the 4500 is the best choice IMO, easy to source, 5 speed, and tough. but as mentioned above, you will most likely have to adapt a chevy master cylinder to your jeep in order to get full throw out of the clutch. though the 4500 is most likely the most expensive choice. the 3500 is not that strong, would probably work however. the 465 is beefy, but only a 4 speed. they are everywhere but being they were designed in the 60's, it shifts like a tranny from the 60's.

I run a 3500 behind mine without any problems. I am using a 95 Jeep master with the Chevy slave. I ordered the fittings from advanced adapters and use a braided Earls line.

Not a bolt on, but the ax15 behind my and my buddies dodge 5.2's are doing fine.

agree on the SM645. have one behind my 454 and there indestructible. they have the 6 to 1 low, granny gear. i have a saginaw behind my 350 sbc in my jeep and wish i had the money to put in a sm465. in fact i have a 465 in my shed but would need to buy the adapter. the other ones listed im sure are the 4 speeds with overdrives and that a great choice too. depends on what your going to be using it for, rock crawling then the 465.
